High-sealing oil supplementing bearing special for silicone oil clutch

Abstract

The invention discloses a high-sealing oil supplementing bearing special for a silicone oil clutch. The high-sealing oil supplementing bearing comprises an outer ring, an inner ring and rollers, wherein a roller path allowing the rollers to roll is formed in the inner circumferential wall of the outer ring and the outer circumferential wall of the inner ring, a rolling cavity is formed between the outer ring and the inner ring, and two sealing parts used for sealing the rolling cavity are arranged between the outer ring and the inner ring; and the two sealing parts are arranged at the two sides of the rollers, an oil supplementing cavity is formed in the outer ring in a hollow manner, the oil supplementing cavity is filled with solid grease, an oil discharging hole for conveying grease is further formed in the outer ring, one end of the oil discharging hole is communicated with the oil supplementing cavity, and the other end of the oil discharging hole is communicated with the roller path on the outer ring; and a blocking part used for dredging the oil discharging hole when the bearing operates and blocking the oil discharging hole when the bearing stops operating is arranged in the oil supplementing cavity. According to the high-sealing oil supplementing bearing, the problems that in the prior art, because the grease in the bearing rolling cavity is used up, the rollers rotate in a dry manner, and the bearing sealing parts are prone to disengaging from the rollers are solved.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a special high-seal oil-supplementing bearing for silicone oil clutches. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Silicone oil clutches are high-precision equipment used in automobiles. They are usually used to control temperature. However, the bearings used in silicone oil clutches in the prior art have poor sealing performance, which often causes external impurities to enter the bearing and cause the bearing to fail. When the bearing is high-speed In the case of running, the failure of the bearing will easily damage the silicone oil clutch; and the high-speed running bearing has a large internal grease consumption, so the operator needs to often supply oil to the inside.
